I am reassembling the right top end after a piston & head replacement and cannot reconnect the temperature sensors wire. Completely baffled… all the other electrical connections work fine, but the wire from the head has a slot on the side (male) and the corresponding harness wire has a slot in t...

I threw an exhaust valve on my 2007 R1200RTP, totally destroyed the head and piston, only very minor nick in cylinder wall, near the top of the cylinder. Found a new head and piston on eBay and cleaned them up. Good tolerances, rings are tight, and I am ready to reassemble. The Haynes manual states ...

2007 R1200RTP seized last fall, finally had time to dig in. Discovered a broken exhaust valve on right side. I’ve watched several videos on how to do a tear down, but all presume the ability to place pistons at TDC and secure the valve drive chain in position, before disassembly. With the engines se...

Had some time to troubleshoot today and the engine is definitely seized. Will not turn over and cannot get the engine to move when I place it on the center stand, put it in gear, and move the back wheel. Can anyone recommend a good resource (manual or video) for an engine rebuild?


Thanks in advance

Thanks for the ideas on where to start. The temperature range was well within normal (less than half mark on a very hot day 33C). Oil level is good. I'll drain the oil and check for particles and pull the plugs and do a compression check and look for damage there.

I've had this 2007 R1200 RTP for about 6 months, been driving it for the last 3 months. Has 34,000 miles on it. It's been running fine, with no problems. Today I was cruising along in 3rd Gear, about 3,000 RPM - in town. All of a sudden I experience as short but very loud rattle, noticeable vibratio...

The main & aux. batteries are the same, if the aux. battery is in better condition than the main battery, how about switching them around. The aux. battery itself has no bearing on the starting circuit of the bike. Great idea, both batteries seem to take and hold a charge, but the Aux is strong...

2007 R1200RT-P: Has 2 batteries, Main and Aux. Each battery has a two-pin cable & plug attached directly to the battery terminals. The main cable & plug is snap tied to the frame. The aux battery cable & plug sits in the top of the sun-glass sized compartment directly above the aux batte...
